re: What has been done in encouraging alternative fuels

Really, fermenting alcohol from agricultural waste like the Brazilians do makes sense, but growning corn to make alcohol???? Has anyone calculated the energy budget for this? You need energy (lots of it) to make the fertilizer, operate the farm machinery to grow it, pump the irrigation water, dry the grain in silos, transport it. This sounds like pork on an astronomical scale and it may wind up consuming more energy than it yields. I have a very bad feeling about this.
